1. A chip-based frequency comb generator disk resonator comprising:
- a chip-based disk resonator comprising a waveguide that is a part of a wedge structure fabricated from a silicon dioxide layer, the disk resonator having a threshold control power of less than 12 mW for a repetition rate ranging from 2.6 GHz for a disk resonator having a diameter of 25 mm to 220 GHz for a disk resonator having a diameter of 0.3 mm.

Abstract
A frequency comb generator fabricated on a chip with elimination of a disadvantageous reflow process, includes an ultra-high Q disk resonator having a waveguide that is a part of a wedge structure fabricated from a silicon dioxide layer of the chip. The disk resonator allows generation of a frequency comb with a mode spacing as low as 2.6 GHz and up to 220 GHz. A surface-loss-limited behavior of the disk resonator decouples a strong dependence of pumping threshold on repetition rate.
